摘要
考虑委内瑞拉瓜里科灌区运行特点、原材料、人力及建筑业水平等因素,采用在渠道原衬砌板上铺土工膜对灌区渠道修复,选取渠道试验段修复设计,提出了土工膜加固方案设计和施工要点。结果表明,该方案修复渠道行之有效,渠道水量损失减少,防渗效果显著。
Considering the operational feature, raw materials, labor and level of construction of Guarico irrigation district in Venezuela, geomembrane laid on the concrete lining plate is applied to recover the channels of irrigation district. The reinforcing program desigff and engineering construction core points are proposed by choosing restoration design of the channel test section. The simulation results show that geomembrane can he effective of channel rehabilitation and reduce water volume loss of channel and raise the seepage prevention effect.
